DVVK-4F FLEX VENT INSTRUCTIONS FOR HORIZONTAL TERMINATION (CONT'D)
5. Determine the length of the vent needed, allowing slightly more
vent then required. Stretch the inner and outer flex vent out to
48 inches, then, trim off the extra length of vent not needed.
NOTICE: If the venting is too long, trim off the excess
venting as needed, however, make sure you leave enough
extra to make the connections at the termination cap.
6. Locate the inner flex vent which has a pre-assembled
flue collar connector and attach the spacer springs by
interlocking the end of the springs about 2 inches. The
springs should be spaced evenly apart starting at 12 inches
from the fireplace flue collar. See Figure 72.
NOTICE: Silicone sealant must be rated for 1000
7. Attach the flex flue (non-connector end) to the Termination
Cap. Use silicone sealant on connection, and secure with the
4 inch dia band clamp.
8. Slip the outer flex vent over the inner flex flue (with spacer
springs), then secure the Inlet Flex vent to the Termination
Cap. Use silicone sealant on connection, and secure with a
7 inch dia band clamp.
9. Feed the Flex pipe (with cap attached) through the wall
thimble assembly from the outside.
10. Secure the termination cap to the house exterior using four
1/8 x 3 inch long screws. Be sure to install the Deflector
Shield with the two screws at the top of the termination base.
See Figure 73.

11. Add sealant to the flue adapter collar, (SD46DVA-FCFX7
sold separately) then insert the adapter collar to the flue
collar on the fireplace. Secure the flue vent collar using four
#6 x 1/2 inch self tapping screws provided.
12. Feed the outer flex vent over the inner flex flue vent and
secure to the 7 inch dia. fireplace collar. Tighten the band
clamp, then seure the clamp to the fireplace with (4) evenly
spaced #6 x 1/2 inch self tapping screws provided.
13. With the fireplace secured, check to make sure that the re-
quired rise (1/4 inch per feet.) of the vent is maintained from
the fireplace and upward through the thimble assembly and
termination cap.
NOTICE:
Do not force the Horizontal Vent Termination into the
flex venting. Always stretch out the venting first, and cut off ex-
cess vent material. Forcing the termination cap into the flex vent-
ing will deform the flue venting, which will restrict the exhaust
gases, and cause improper operation of the fireplace.
